An update that solves three vulnerabilities and has two security fixes can now be installed.

Description:

This update for glibc fixes the following issues:

• CVE-2020-1752: Fixed a use after free in glob which could have allowed a local attacker to create a specially crafted path that, when processed by the glob function, could potentially have led to arbitrary code execution (bsc#1167631).
• CVE-2020-1751: Fixed an array overflow in backtrace for PowerPC (bsc#1158996).
• CVE-2020-10029: Fixed a stack buffer overflow during range reduction (bsc#1165784).
• Use 'posix_spawn' on popen preventing crash caused by 'subprocess'. (bsc#1149332, BZ #22834)
• Fix handling of needles crossing a page, preventing incorrect results to return during the cross page boundary search. (bsc#1157893, BZ #25226)
